Pervasive SQL v12 or later is recommended for CertiflexDimension users with five or more concurrent users. The Pervasive SQL client/server architectures provide many benefits, such as more efficient distributed processing, high performance, enhanced data integrity and reliability, remote access support and scalability.

Wireless Networks are not recommended

Experiments have shown that performance degrades in the wireless networks as compared to wired networks. The main reason is that wireless networks errors are often caused by many factors, such as the effects of fading, interference, and mobility. The communication characteristics of wireless links such as limited bandwidth, high latencies, high bit error rates, and temporary disconnection caused by user mobility and handoffs, makes them not suitable for transactional processing software. Security is also an issue in many wireless connections.

We strongly recommend that one computer is dedicated as a server. Meaning no one should do any processing on it. In almost all cases the long-term benefits of lower downtime, reduced risks of data corruption and system crash far outweigh the cost of an extra computer.
